METHOD OF TREATING PICTURES Filed Dec. 12, 1928 @J in J W (3 5 (5 5 18 A ()1 I 11 h A A (I 1) 6 5 Patented Mar. 25, 1930 THOMAS L. LATTER, OF CHICAGO, ILLINOIS METHOD OF TREATING PICTURES Application filed December 12, 1928.

This invention relates to improvements in the method of treating pictures, and is more particularly applicable to the treatment of prints, pictorial illustrations, and the like,

such as lithographs, engravings, electrotypes,

and the like.

One of the features of my invention is to so treat the surface of a smooth picture that it will simulate the appearance of canvas and give an oil painting effect to the picture. My improved method of treating pictures also brightens the colors of colored prints and provides a glossy surface which will resemble oil paintings.

For the purpose of illustrating my invention, I have shown certain apparatus in the accompanying drawing, in which:

Figure 1 is a view in perspective of a roller used for spreading the adhesive on the picture.

.Fig. 2 is a vertical sectional view of a press.

Fig. 3 is a vertical sectional view of means for heating the picture, and

Fig. 4 is a fragmentary view in perspective on an enlarged scale of the face of the picture after it has been treated by my improved method.

In carrying out my improved method the first step consists of applying to the face of the picture a thin even film of a suitable adhesive or base, which, for example, be crude petroleum thinned with banana oil to about the consistency of Vaseline. Such adhesive may be applied in any suitable man ner. For example, the picture, as indicated by 10, may be placed upon a suitable fiat support 11 with its face upward. A suitable amount of the ahesive or base, such as crude petroleum, suitably thinned, may then be placed on the face of the picture. 12 indicates a suitable roller, for example, a rubber roller such as is used on a printing press. By rolling this roller back and forth over the face of the picture, the crude petroleum may be evenly spread over the face to give a thin film.

The picture 10 is then placed on the base 13 of a suitable press and a sheet of fabric 14, for example, canvas laid over the face of the picture on top of the thin coating of adhesive.

Serial No. 325,512.

The cover 5 of the press is then pressed downwardly as, for example, by means of the screw '16, to press the fabric 1ft tightly against the face of the picture.

The fabric 14 chosen may be anything desired to give the desired resulting appearance to the picture.

For

example, it may be canvas and then will make the face of the picture resemble the texture of CZLHVELS.

Different kinds of canvas, or cloth,

or other material, may be used to give desired effects.

The mesh and weave of the canvas other material used will be impressed more placed on a hot plate 17 heated by means of suitable burners 18. The heating should be enough to melt the shellac but not to burn or discolor the picture.

I have found that in some cases a heat of 500 F. is suflicient to cause the shellac to melt and become transparent and not injure the picture. Pressing the canvas on the adhesive causes such adhesive to take more or less the appearance of the texture of the canvas; and the powdered shellac will also adhere to the adhesive and resemble such texture. The heating then causes the shellac to become transparent, thus giving the face of the picture the appearance of the texture of the canvas of the fabric 14: that was used. In Fig. l, I have attempted to indicate more or less diagrammatically the appearance of the face of the picture 10 after my process has been completed.

By treating a print or picture in accordance with my improved method, it may be made more durable and waterproof. \Vaterproofing the picture also permits it to be more readily cleaned without injury.

lVhile I have shown and described certain embodiments of my invention, it is to be understood that it is capable of many modifications.

Changes, therefore, in the construction and arrangement may be made Without departing from the spirit and scope of the invention as disclosed in the appended claims,

in Which it is my intention to claim all novelty inherent in my invention as broadly as possible in View of the prior art.

I claim:

1. The method of treating a picture or print consisting of applying an adhesive to the print, adjusting the adhesive to simulate the appearance of a desired texture, applying a powdered finishing material to the adhesive, and baking the finishing material to form a permanent gloss. v

2. The method of treating a picture or print consisting of applying an adhesive of thinned crude petroleum to the face, pressing a sheet of fabric against the adhesive, applying powdered shellac to the adhesive, and baking the shellac.

3. The method of treating a picture or print consisting ofapplying a thin coat of adhesive to the face thereof, pressing a sheet of fabric against said adhesive, applying powdered shellac to the adhesive, and baking the shellac to melt the same.

4. The method of treating a picture or print consisting of applying a thin coating of adhesive to the face thereof, pressing a sheet of fabric against the adhesive to leave an imprint of the texture of the fabric in said adhesive, applyingpo-Wdered shellac to the adhesive, and baking the shellac to melt the same.

5. The method of treating a picture or print consisting of applying a thin coating of adhesive to the face thereof, pressing a sheet of fabric against the adhesive to leave an imprint of the texture of the fabric in the adhesive, and'applying a suitable finishing material to the adhesive.

6. The method of treating a picture or print consisting of applying a thin coating of adhesive to the face thereof, pressing a sheet of fabric against the adhesive to leave an imprint of the texture of the fabric in the adhesive, applying a suitable powdered finishing material to the adhesive, and baking the finishing material to melt the same to form a permanent gloss.
